Confident, comfortable, fast and simple. Best bike around for the price.


Wulf - Core-Line

Great buy for a fixie/freewheel bike.

Cost is great for someone on a budget. Nice bicycle that will get heads turning when you ride it.

Great price but that comes at a price

As I was putting the bike together it became clear that it wasn’t assembled very well. The headset was notchy as was the bottom bracket and one of the pedals. I ended up taking the headset apart to put the appropriate amount of grease in the bearings. I am going to ride it a bit before I tackle the B.B. I replaced the pedals with clip less anyway so that didn’t matter. Otherwise I like the look of the bike and look forward to riding it.

Wulf Bike Review

The Wulf Bike is really great. It rides smooth and feels safe. I rode single speeds back about 10 years ago and have since returned to riding. The Wulf was the right choice. I ride it single speed and it is fast and stable. I ride in Brooklyn and it can get pretty hectic out here but what I love about this bike is how light and responsive it is. On top of all of this the bike also looks great. You can not go wrong with this bike, especially at such an affordable price. I had to exchange my bike, as I needed a medium and not a large, and the exchange process was smooth. The customer service was efficient. I recommend this bike if you are looking for a solid, lightweight, and affordable single speed bike.

Best Value Bike on the Market

Hands down a good quality bicycle. There are only two upgrades I would make: 1) the bike pedals seem rather cheap and 2) upgrade the crank to something more substantial (as posted by another user). However, at this price point for a new bike, I'm very impressed. Piecing the bike together was intuitive and simple. I find the saddle to be very comfortable. What's more was that the customer service folks I corresponded with were attentive and quick to respond. Plus, I got a free backpack out of the deal. Very easy five star rating!
